may someone help me with this problem? Thank you!

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's find the value of given expression for x = 5 ~

$\qquad \sf  \dashrightarrow \:3(3x + 5)$

$\qquad \sf  \dashrightarrow \:9x + 15$

now, plug in the value of x as 5

$\qquad \sf  \dashrightarrow \:9(5) + 15$

$\qquad \sf  \dashrightarrow \:45 + 15$

$\qquad \sf  \dashrightarrow \:60$

so, the equivalent value is 60
